REF 2029 portability ends automatic transfer of most research outputs when staff change institutions. Outputs are now “decoupled” from individual authors and instead require a demonstrable “substantive link” to the submitting institution, with one exception: long-form outputs such as monographs stay portable with the author for five years. The rule, confirmed by the four UK funding bodies in December 2025, replaces the dual-submission compromise used in REF 2021.
Portability, in REF terms, is the rule set that determines which institution — the one a researcher has left, or the one they have joined — may submit a given research output for assessment. REF 2029 narrows that rule further than any previous exercise, and the change has become one of the most contested elements of the framework’s redesign.

What REF 2029 Changes for Portability
REF 2029’s initial decisions, published in 2023, “decoupled” research outputs from the individual researchers who produced them. Where REF 2021 attributed outputs to named staff on a submission list, REF 2029 requires only that a submitting institution demonstrate a substantive link to the output — evidence that it supported the underlying research.
Research England’s Head of REF Policy has described this as a shift toward assessing “how well organisations are supporting research excellence” rather than tracking individual output counts. In practice, that means the REF volume measure and staff lists are no longer the sole determinants of which outputs an institution may submit.
How the Substantive Link Rule Works When Staff Move
For standard outputs — journal articles, conference papers, most datasets and software — the substantive link is generally established by an eligible employment relationship between the institution and the author when the research was conducted or the output first made publicly available. Once a researcher leaves, that link does not automatically transfer to their new employer.
This is a marked departure from REF 2021, which let both the origin and destination institution return an output where a researcher transferred, and from REF 2014, where only the destination institution could submit if the move happened before a single census date. The table below sets out how the rule has moved across three cycles.
| REF cycle | Portability rule | Long-form treatment |
|---|---|---|
| REF 2014 | Single census date; only the destination institution could submit if a researcher moved before it | No separate treatment |
| REF 2021 | Compromise rule: both origin and destination institutions could return the same output on transfer | No separate treatment |
| REF 2029 | Outputs decoupled from individuals; standard outputs require a substantive institutional link and are not portable | Portable for five years if the new post began within that window |
The REF 2021 compromise itself had a contested history: Lord Stern’s 2016 independent review of the REF recommended full non-portability, but Research England judged that too significant a change to introduce that late in the REF 2021 cycle, and adopted dual submission instead.
Why Long-Form Outputs Get a Five-Year Exception
On 10 December 2025, following a three-month pause and intense sector pushback, REF 2029 published updated guidance restoring limited portability for “long-form and extended-process” outputs — monographs, edited collections and scholarly editions. These remain attached to the author for five years, provided the researcher’s employment at the new institution began within that window.
According to Times Higher Education’s reporting on the announcement, institutions can deploy this exception where the academic was employed at some point during a two-year staff census window that opened in September 2025 — though commentators on that same report disputed how directly the census window bears on long-form eligibility, underlining how unsettled the operational detail still is.
Reaction split along familiar lines. Jennifer Richards, chair of the English Association and professor of English literature at the University of Cambridge, called herself “delighted that an element of portability has been restored,” describing it as “a ‘win’ for all researchers in a sector that has become increasingly precarious at every stage of career.” Margot Finn, vice-president for higher education and research at the British Academy, called the concession “excellent and very welcome.” Rosa Freedman, professor of law at the University of Reading, was less convinced, arguing the “half in-half out” approach “doesn’t seem to have much logic” and that outputs should belong either wholly to the employer or wholly to the researcher.
What the Sector Consultation Flagged as Unresolved Risk
Sector consultation ahead of the December 2025 decision surfaced risks that the rule change does not fully resolve. Institutions can still retain long-form outputs credited to staff they have since made redundant — a concession the reversal did not touch. Several concerns recur across the consultation record:
- Early-career and precariously employed researchers lose standard outputs as a bargaining tool when applying for new posts, since those outputs no longer travel with them.
- Redundant staff may see their long-form outputs retained and submitted by an institution that has already ended their employment.
- Co-authored outputs where authors move to different institutions raise unresolved questions about which institution’s substantive link takes precedence, particularly where authorship attribution is contested.
- Discipline-specific impact: arts, humanities and social science bodies — including the English Association, the Institute of English Studies and University English — wrote jointly to flag that decoupling disproportionately affects fields where long-form outputs and precarious contracts are both common.
A joint Wonkhe analysis by academics at the Royal Central School of Speech and Drama, the University of Oxford and the University of Edinburgh went further, warning that decoupling removes any auditable limit on how many outputs by one individual a unit can submit, which they argued undermines the diversity-of-contribution goal the rule change was partly designed to serve.
Common Questions on REF 2029 Portability
What period does REF 2029 cover?
REF 2029 runs on an extended timetable after the exercise was renamed from REF 2028 to REF 2029 in a December 2023 decision. The criteria-setting phase runs to summer 2026, the assessment phase is planned for winter 2028 to autumn 2029, with results published in December 2029.
What outputs are eligible for REF 2029?
Standard outputs are eligible where the submitting institution demonstrates a substantive link — typically an eligible employment relationship with the author when the research was conducted or first made public. Long-form outputs, such as monographs, remain eligible at a new institution for five years after the researcher’s move.
What is the weighting for REF 2029?
REF 2029’s December 2025 guidance weights Contributions to Knowledge and Understanding at 55% of the overall quality profile, Engagement and Impact at 25%, and Strategy, People and Research Environment at 20%, shifting emphasis toward institutional research culture rather than individual output counts.
Is it REF 2028 or REF 2029?
It is REF 2029. The four UK funding bodies renamed the exercise from REF 2028 to REF 2029 in December 2023, extending the assessment timetable to give institutions more time to adjust to decoupling, open access and portability rule changes ahead of results in December 2029.
What Institutions Should Do Next
Research administrators handling staff transfers should treat the substantive-link test, not the researcher’s current employer, as the operative question for every output under consideration. That means auditing when each output’s underlying research was conducted or first made public, and mapping it against the employment record at that time — a task that sits squarely with research administration teams managing REF submission pipelines.
For long-form outputs, institutions should document the five-year window and the justification for classifying a work as “long-form and extended-process” at the point of hire, not retrospectively. Because the rule change also reopens questions about how authorship attribution interacts with institutional submission rights, joint appointments and co-authored outputs deserve particular scrutiny before the assessment phase begins in 2027.
The sector consultation record makes clear that portability remains an unresolved fairness question, not a settled technical rule. Institutions that build audit trails now — rather than waiting for further REF guidance — will be better placed when panels begin assessing submissions from 2028 onward.
